The objective of this study is to separately demonstrate the safety and efficacy of BIOTRONIK's Astron and Pulsar stents. The Pulsar stent will be used for the treatment of femoro-popliteal lesions, located in the native superficial femoral artery (SFA) or proximal popliteal artery (PPA), while the Astron stent will be used for the treatment of the common or external iliac artery lesions.
